开发FPGA的入门程序.是一个4个LED点亮程序

MAX7219驱动LED特好使.MAX7219是微处理器和共阴极七段― ― 八位LED显示、图条／柱图显示或64点阵显示接口的小型串行输入／输出芯片。片内包括BCD译码器、多路扫描控制器、．字和位驱动器和8X 8静态RAM。外部只需要一个电阻设置所有LED 显示器字段电流。MAX7219和微处理器只需三根导线连接，每位显示数字有一个地址由微处理器写入。允许使用者选择每位是BCD 译码或不译码。使用者还可选择停机模式、数字亮度控制、从1～8选择扫描位数和对所有LED显示器的测试模式。-LED Driver MAX7219 so special. MAX7219 is a microprocessor and a total cathode seventh-- 8 LED display, map article/column or 64 shows a small dot-matrix display interface serial input/output chips. Chip including the BCD decoder, multiplex scan controller. Word and bit drive and 8X 8 static RAM. External resistor only need one set all LED displays current field. MAX7219 and the microprocessor only three wires to connect, each show has an address by the digital microprocessor write. Is to permit users to choose each BCD decoding or not decoding. Users can also choose to shutdown mode, the digital brightness control, 1 ~ 8 to choose from scanning the median and LED displays for all the test mode.

经常去论坛的朋友可能都有这样的体会，当看到好的帖子特别是贴图时，想 把它转贴到另一个论坛特别麻烦，要进行好多鼠标与键盘操作，当有上十张图片 时真是令人头痛的事情。 此软件就是针对这种情况而设计，你只需要在想要的图片上点一下鼠标就可 提取图片链接并形成论坛UBB标签，进入发贴页面再点一下鼠标就可将获取的内容 发出去。使用该软件使以往烦琐的转贴操作变得轻松简单，你就尽情的享受从中 带来的乐趣吧！ -often went to the Forum and friends may have such an experience when you see a good message, especially textures, wants to turn it into another forum posted particular trouble, the need for a lot of mouse and keyboard operation, when on 10 pictures is really a headache thing. This software is the view of this situation and design, you only need to want to point the pictures from the mouse can link pictures and formed Forum UBB label, sent into the pages again point the mouse can be given access to the content. The software enables the use of previously cumbersome operation posted becomes easily, you enjoy the fun from the fun!

提出了一种基于样本的分级检索 MPEG 视频的新方法:首先用I 帧的dct_dc_size 字段快速粗检,然后用断层摄影(tomography)法分析B 帧运动矢 量的时空分布特性以进一步缩小结果集,最后用DC 图像的精确匹配方法验证检索结果.试验结果表明,本方法 所需计算量较小,且可保证较高的检索精度.-presents a sample classification based on MPEG video retrieval of the new method : First of all I frame with the rapid field dct_dc_size rough Frederick, and then use tomography (tomography) Analysis of B pictures motion vector space-time distribution to further narrow the results set, and DC Images precision Matching test results retrieval. test results showed that the calculation method for small and can guarantee higher retrieval accuracy.
